This is an excellent, all round exercise for the trunk/core known as the front plank. The goal is to hold your body rigid from shoulder to toe, like a ‘plank’ of wood. It is particularly useful as it trains every muscle in the trunk from the “six pack” muscles at the front, to the muscles underneath your love handles, round to the muscles of the lower back. There are, in fact, very few muscles in the body which are not engaged in plank.
Before trying a Plank on the Power Plate it's a good idea to get used to performing the exercise on the floor, see the Beginners' Guide to the Abdominal Plank for illustrated instructions.
You can make the front plank more challenging by elevating the feet on to a step or stability ball, or perform the exercise with one leg, or one arm help up from the floor. Generally the plank is a static exercise, where you simply hold the position without moving.
If you have an abdominal hernia or any issues relating to the spine on back generally this should only perfomed under the supervision of a fitness professional.
How to do a plank on the Power Plate:
• Place flexed elbows on the plate and engage the abs (tummy muscles), glutes (buttocks) and hamstrings (back of the legs) as you extend.
• Maintain a strong core and neutral spine alignment from neck to feet.
• Aim to hold the position for 30 seconds the first time you try it, working up to being able to maintain it for a minute.
